Hi Andrew,

CCing to the ufo devel list, as this might be interesting for others as well.

Well, might be a bug. I have to review the X11 driver ...
But you could try to set all window parameters before calling setVisible. 
Perhaps some attributes are not updated after creating the window.

To modify the window frame, you have to adjust the frame style attribute:
UXFrame::setFrameStyle
(see ufo/ufo_types.hpp, enum FrameStyle).

The GLX driver uses the motif window hints to indicate which frame style the 
window manager should use (see src/ux/uxglxdriver, line 1031).

Perhaps it works if you play around with the frame style parameter ...

The maximize button should already be hidden when the window isn't resizable 
anymore.

Try to make setVisible(true) the last command.
SDL and probably some UFO drivers don't like it if window parameter are set 
after the window is shown.
